Sprayer nozzle material should be selected based on the pesticide formulation.

• A. Nozzle material should be selected based on the pesticide formulation.
• B. Nozzle material is chosen based on price alone
• C. Nozzle material is chosen based on the color of the nozzle
• D. Nozzle material is chosen based on the spray color preference

Answer: (A)

Nozzle material must be compatible with the pesticide formulation to prevent corrosion, degradation, or clogging that would distort spray performance. Different formulations have varying chemical properties—acidity or alkalinity, solvents, and additives—that can attack metals or plastics. If the wrong material is used, acidic formulations may corrode brass or corrosion-prone alloys, certain solvents can soften or crack plastics, and aggressive mixtures can wear down orile flow orifice shapes, changing droplet size and spray pattern. Choosing the right material helps maintain nozzle life, accurate droplet distribution, and safe application.

Prices, color, or appearance do not reflect chemical compatibility, so they aren’t reliable indicators for selecting nozzle material.
